 Synopsis:

Abstract:
The lecture aims at introducing the students to the Feynman’s functional integral and its applications. The focus is on broadening the knowledge of modern parts of relativistic and nonrelativistic Quantum Field Theory and statistical physics. The content of the lecture can serve as a base for further study in fields of exactly solvable models, theory of critical phenomena, molecular chemistry and biochemistry or quantum gravity.
